Figure 1. GENERAL DESCRIPTION The ADL5592 is a digitally programmable variable gain amplifier (VGA) designed for use from 250 MHz to 2400 MHz. Two digitally programmable attenuators are cascaded with a high linearity fixed-gain amplifier. The device also includes a mixer, which can be used to mix the transmitted signal into an adjacent receive band for loopback testing. The ADL5592 can be used in conjunction with a direct-to-RF modulator, such as ADL537x and ADL539x, in cellular munications systems such as GSM/EDGE. The ADL5592 is available in a 6 mm × 6 mm, 40-lead exposedpaddle LFCSP package. The device operates from the - 40°C to +85°C temperature range.
